ABSTRACT:
A wobble drive mechanism for a translationally moving structural part includes a wobble rod which is moved by way of a crank drive mechanism. The wobble rod includes a spherical section at one end thereof that is seated in a bearing bush of a crank. At its opposite end, the wobble rod includes a second spherical section that is seated in a stationary structural part. A third spherical section is positioned between the two ends of the wobble rod and is seated in the translationally moving structural part. The spherical sections are supported in hemispherical articulation sockets located in the manner of a mirror image in the two structural parts. A spring device can be provided to ensure full contact of the spherical sections in their respective articulation sockets.
